Why a telephone case?

It is worth mentioning that even cheap cases protect your smartphone from falling and can offer a grip by preventing you from dropping the phone in the first place. Many telephones have a particularly smooth back. Even if you're not worried about a single scratch or even dropped, there's more to your phone than that. Some phones (such as the iPhone) have a camera lens that is flush with the back, which means that it is much more likely to be scratched and damaged, making your photos look very bad. You can also damage one of the buttons on your phone, making it much harder to use than just a few scratches.
